VALV E-LIFTEB.

To all lwlw/m, t may concern.'

Be it known that I, LEWIS H. HoLcoMB, a citizen of the United States ofAmerica, residing at Columbus, in the county of Franklin and State ofOhio, have mvented certain new and. useful Improvements 1nValve-Lifters, of whichA the following is a specification.

The presentinvention relates to lmprovements in valve lifters for use inconnection with internal combustion engines for the purpose of liftingthe valves from their seats in order to gain access to certain parts ofthe engine, for replacing valves, etc without the necessity of long,tedious work and resort to laborious proceedings and handllng of thecylinder or motor as is frequently the case.

The primary object of the invention is the provision 0f a tool that maybe handled with facility, by one person, that is'compact and durable,efficient, and capable of v adjustment so that it may be used in places,

ordinarily diiiicult of access, with facility.

The invention consists incertain novel combination and arrangements ofparts as will be fully -described and claimed and as illustrated in theaccompanying drawings. I have depicted one complete example of thephysical embodiment of my invention constructed according to the bestmode I have so far devised for the practical application of theprinciples of my invention, and

- while I have illustrated and shall describe the device as a valvelifter, it will of course be understood that I shall avail myself of allthe usesto which the implement may be subjected, and that the device maybe altered within the scope of my claims.

Figure 1 is a side elevation of a device made according to my invention.Fig. 2 is a top plan view of the device of Fig. 1, showing in dottedlines the capability of adjustment of the device. Fig. 3 is a plan viewof 'a different sized jaw by which the implement may be adapted for usewith different sized valve stems etc. Fig. 4 is an edge view of the jawof Fig. 3, showing in dotted lines the xed jaw of the tool. Fig. 5illustrates the use of the implement (shown in dotted lines) as appliedto an exhaust valve of an internal combustion engine, the spring of thevalve being shown as compressed. K i

In the preferred embodiment of the invention as illustrated inthedrawings I Specification of Letters Patent.

Application filed April 22, 1915. Serial N0. 23,058.

have shown two vparallel jaws l1 .and 2, the former a movable orslidab-le one and the latter stationary, or fixed with relation to thejaw 1. The movable jaw is slidable on the post 3 which is rigid with and`lixed to the jaw 2, and the post is grooved at.4 for accommodation ofthe feather 5 carried by the sleeve 6 of the jaw 1. In this manner thejaw 1 through the 6 is movable or slidable on the post, but lateralmovementdof -the jaw with relation to the post is prevented bytheengagement of the feather of the jaw inthe groove of the post. By thisarrange-- ment and combination of parts it will be seenthat the movablejaw is capable of a direct and straight motion with relation to the Xedjaw so that, when compressing the valve spring 7 the spring is moved ina dis rectline and is held against deviation. This is a most desirablefeature of the invention as it prevents the accidental displacementof-the spring when the latter is unsupported.

The jaw l is moved through the medium of a pair of lever handles 8 and9, the former pivoted at 10 in a fulcrum link 11 and pivotally connectedat 12 to a bolt 13 swiveled in a bracket arm 14' integral with andprojected from the sleeve of the movable jaw.

The two handles or levers 8 and 9 are made preferably from stampedmetal, the sections of each handle being joined together by rivets as 15while the operating ends of the handles are forked or spread apart toaccommodate the link 11 and their swivel bolts. The link 11 as clearlyseen is a metallic strip fashioned with a series of fulcrum holes 16 toreceive the pivot pin 10, and-at 17 the link is pivoted in the leverhandle 9i The lever handle 9 is in turn pivoted at 18A to the bolt 19which is swiveled in the bracket arm 20 directly in line with andbeneath the swivel bolt 13 of the lever 8. A lug 21 is provided on thehandle 9 t0 retain the handle 8 when the jaws are held open. Both thejaws have mouths or cut away portions as 22, and in Fig. 2 the mouth orcut away portion is of a size to span or fit around a large size valvestem 23, but to adapt the implement to smaller size stem, I employdetachable supplemental jaws 24 as illustrated in Figs. 3 and 4. Themouth 25 of such a and the supplemental jaw is formed with jaw is madeof smaller dimensions',

'2 i,w'hnaaaYA l valve stems; and they held by the bolt 2,8 passedthrough the o'penside flanges v26 and lcentral. lugs 27 so that thesupplemental jaw mayv be slipped over lthe jaws 1 or 2 and secured by aset bolt 28 tothe first jaw. A In this manner the jaws are adapted tothevariable diameters of may be detachablyv ing 29 in the jaw 24.

In Fig. 2 the. radius-of movement ofthe jaws upon their "swiveledsupportsis indicated by the dotted circular line, and it will be seenthat the jaws may be bodily and synchronously turnediupon their swivelsupports throughout a wide radius Lthus enabling the device to be usedwith facility in other wise inaccessible and difficult places.

By means of the series of openings 16-in the link 11 the fulcrum pointof the lever 8 may be altered "and the movement of 'the slidable jawwith relation to the xedjaw may be adjusted to adapt the device for usewith diierent sized valve accessories.

In usn the device, the two jaws are in closed position, in contact, withthe two handles spread apart. The fulcrum bolt 10 of course has beenproperly adjusted to the required height, and the swiveled jaws havebeen swung around to the proper angle in order to get at the valve stemand spring in proper position. The lever handles are now brought1together bv swinging the handle 8 on its pivot or fulcrum bolt 10 andthis action raises the movable jaw 1 so that it slides A upwardly on itspost while the jaw 2 'remains stationary resting uponvthe-ixed por# tion30 of the valve devlce. As the movable jaw, is raised it lifts the loosecollar 31 of the stem and thus compresses the spring 7 so that accessmaybe had to thecotter pm I 32 (dotted lines Fig. 5)' or other attentiongiven to the valve device as required. The

lever arms are held in position by crossing one over the other andpermitting thefe'ndof' lever 9 to rest between'the lugs 21, and thelever 8 to which it is fixed. l ,In'this manner the spring is heldcompressed and the: handsare free to perform the work frequlred'.

What I claim is l 1. A device as described Ictn'n'prisiiig v ofpivotally joined lever handles, a pair of jaws one of which has astraight line movement relative to the other, and a swiveljointl betweeneach jaw and its handle ,permitting the jaws to swing at right anglesftothe plane of the handles.. I v A I 2. A post a jaw fixed thereon and ajaw slidable on the' post, apair of. lever vhandles pivoted to the `jaws and pivoted together,-

and a swiveljoint between the handles and jaws.

3. A, post a jaw fixed thereon and a par-V allel jaw slidable on thepost, a pair of lever handles pivoted to the jaws, and an adjustablepivotal link connecting said handles,

and a swivel joint between ea h handle and its jaw.

In testimony whereof I aix my si ature.
